I cannot access MS Outlook on my android telephone phone.

Try these steps on the Android phone:

1. In Outlook, go to Settings > tap the account that is not syncing > tap Reset Account.
2. If that does not help, go to Settings > tap the account > Delete Account > Delete From This Device. Then add the account again in Outlook for Android.
3. If calendar or contacts are missing, make sure the account is added as Exchange and not IMAP. On Android, check Settings > Accounts > tap Exchange > tap the email account, and confirm Sync Calendar is enabled.
4. If Outlook cannot add the account or stops syncing new messages, check Android power settings:
   • Turn off power-saving mode.
   • Disable power optimization for Authenticator or Company Portal so it can run in the background.
   • Open Authenticator or Company Portal before opening Outlook.
   • On Huawei devices: Phone Manager > Auto-launch > Secondary launch management > enable Authenticator/Company Portal.
5. If the account is an Outlook.com, Hotmail, Live, or MSN account, check the Outlook.com service status first.
6. If sign-in still fails, use the in-app support option in Outlook and select Contact Support.

If the account is a work or school Microsoft 365 or Exchange account, contact the Microsoft 365 admin or technical support.
